I cannot run any Neper command

[Sofia-Y]

Hello, folks!

Did anyone get an error such as the following one below?
I am not sure what to do, I installed the new Gmsh module version and all went well but when I try to run any simple Neper example, it does not want to.

No idea what this is. How did you install Gmsh?

The problem was indeed Gmsh. I had to re-install it to get rid of this issue. Thanks for your assistance.
